Ulerõhk

Ulerõhk, often translated as "overpressure," refers to a condition where the pressure within a confined space exceeds the surrounding ambient pressure. This phenomenon is encountered in various fields, including engineering, physics, and medicine. In engineering, ulerõhk can be a deliberate design feature, such as in cleanrooms or pressurized cabins of aircraft, to prevent the ingress of contaminants or to maintain a stable internal environment. Conversely, it can be an undesirable consequence of processes like combustion or explosive decompression, leading to structural damage.

The concept of ulerõhk is governed by fundamental physical principles, including Boyle's Law and Charles's Law, which describe the relationships between pressure, volume, and temperature of gases. In medical contexts, ulerõhk can refer to elevated pressure within the body, such as in cases of high blood pressure (hüpertensioon) or increased intracranial pressure. Understanding and managing ulerõhk is crucial for safety, efficiency, and health across diverse applications. Measurement of ulerõhk typically involves the use of pressure gauges and sensors calibrated to detect deviations from atmospheric or baseline pressure.
